Filter cartridge lifetime computer for
BAUER filter systems - P21 P31 P41
Operating Instruction Manual

Introduction
Read these operating instructions carefully before using the
B-TIMER. (Valid for devices from version 300.301.811 onwards).
The settings in the setup menu are critically
important in terms of the ability to display the
filter capacity correctly. Without these
settings, the B-TIMER can only be used as an operating
hours counter!
Ensure that the compressor’s pressure
retention valve is set to 150 bar (factory
setting) and that it is functioning correctly,
otherwise the filter capacity may be displayed incorrectly
and the operation may not, under certain circumstances,
be detected correctly.
Before
delivery,
ensure
that
all
the
maintenance counters (a+b+c) have been
reset. (Otherwise, the B-TIMER signalises
incorrect maintenance intervals, since the storage times
are not taken into consideration.) If the items in question
have not been reset, it must be done without delay. Refer
to the
‘Reset’
section on page 4.
DESCRIPTION
The
B-TIMER
(Figure 1) is a self-activating mini-computer that
keeps track of the compressor’s operating hours and calculates
the filter cartridges’ lifetime with the help of the time, the
temperature, the type of cartridge and the delivery quantity of
the compressor. It displays the operating hours, the cartridge’s
service
life
and
the
compressor’s
upcoming
maintenance-related tasks. The
B-TIMER
needs neither an
external power supply nor a connection to the compressed air
system. It is mounted on the enclosure of the filter to be
monitored with the help of a fastener and is thus the ideal
monitoring device for all mobile BAUER compressors. It is
particularly well-suited for sport-diving devices that are
powered by either gasoline or diesel fuel. Every system of
BAUER-KOMPRESSOREN can easily be retrofitted with the
B-TIMER.
Intended usage
This device serves solely as an appliance that can be used to
display the operational status and does not release the user from
the additional responsibility to monitor and measure the
breathing air quality of the filter system in accordance with
national norms (e.g. EN 12021). This
cannot
be done with the
B-TIMER.
The
B-TIMER
may only be used with BAUER compressors,
BAUER processing plants and original BAUER filter cartridges. It
has only been designed and approved for the aforementioned
BAUER
filter systems, not for the Verticus and Mini-Verticus
plants. The respective cartridge numbers are contained in the
software. Every other type of utilisation counts as utilisation that
is not in accordance with the regulations. Damages resulting
from such utilisation are subject to the manufacturer’s/supplier’s
risk exclusion, warranty exclusion and liability exclusion policies.
In case of external filter cartridges, even those of similar
dimensions, the service life can deviate significantly from the
intended service life on account of, e.g. different filling materials
and fill quantities. Secure and correct functionality cannot be
guaranteed for compressors and filter systems produced by
other manufacturers, as the compressed air in these items may
be at different temperatures and the efficiency of the upstream
final interceptor may be different. The B-TIMER has only been
tailored to the interaction between BAUER compressors, BAUER
filter systems and original filter cartridges.

Installation
Use the enclosed fastener to mount the B-TIMER at the centre
of the gold-coloured filter’s enclosure. In case of the P41, mount
it on the grey micro-filter’s enclosure. Both its legs must lie on
the container. Ensure that it does not come into contact with
the filter’s fastening clamps. If the B-TIMER needs to be
remounted, e.g. during the replacement of the filter’s
enclosure, ensure that the underside of the heat conduction pad
has not been damaged.
